2. Safety
This product has sharp edges, which may cause serious injury. To avoid injury, handle sharp edges with caution and always use proper protective clothing and equipment.
General Safety Statement
Our foremost concern is your safety and the safety of others associated with grain handling equipment. This manual is to help you understand safe operating procedures and some problems that may be encountered by the operator and other personnel.
As owner and/or operator, you are responsible to know what requirements, hazard s, and precautions exist and inform all personnel associated with the equipment or in the area. Safety precautions may be required from the personnel. Avoid any alterations to the equipment, which may produce a very dangerous situation, where SERIOUS INJURY or DEATH may occur.
You should consider the location of the bin site relative to power line locations or electrical transmission equipment. Contact your local power company to review your installation plan or for information concerning required equipment clearance. Clearance of portable equipment that may be taken to the bin site should also be reviewed and considered. Any electrical control equipment in contact with the bin should be properly grounded and installed in accordance with National Electric Code provisions and other local or national codes.
This product is intended for the use of grain storage only. Any other use is a misuse of the product.
Sidewall bundles or sheets must be stored in a safe manner. The safest method of storing sidewall bundles is laying horizontally with the arch of the sheet upward, like a dome. Sidewall sheets stored on edge must be secured so that they cannot fall over and cause injury. Use care when handling and moving sidewall bundles.
Personnel operating or working around equipment should read this manual. This manual must be delivered with equipment to its owner. Failure to read this manual and its safety instructions is a misuse of the equipment.

2. Safety
Proper Storage of Grain Bin/Silo Materials Prior to Construction
Wet storage stain (rust) will develop when closely packed bundles of galvanized material, such as sidewall and roof sheets, have moisture present. Inspect roof and sidewall bundles on arrival for any moisture. If moisture is present, it must not be allowed to remain between the sheets. Separate the sheets or panels immediately and wipe them down. Spray with a light oil or diesel fuel.
If possible, sidewall bundles, roof sheets and other closely packed galvanized materials should be stored in a dry, climate controlled building. If outdoor storage is unavoidable, the materials should be stored so that they are raised above the ground and vegetation. Any stacking and spacing materials should not be corrosive or wet. Be sure to protect materials from the weather, but permit air movement around the bundles if possible.
Storing roof bundles and sidewall sheets at a slight incline can also help minimize the presence of moisture. Storing the bundles with the center of the dome up (like an arch) is one option for minimizing moisture during storage. Sidewall bundles can also be stored on edge but must be secured so that they do not fall over and cause injury.
If “white rust” or “wet storage stain” occurs, contact the manufacturer immediately about ways to minimize the adverse effect upon the galvanized coating.

4. General Information

Bulk Feed Tank Assembly Manual General Instructions
This product is intended for the use of storing feed only. Any other use is a misuse of the product. While every effort has been made to keep the edges from being sharp, please wear the proper protective
clothing while erecting the Bulk Feed Tank. Our company recommends that you contact the local power company and have a representative review
the installation so the wiring will be compatible with their system and so that you will have adequate power supplied to the unit.
A Bulk Feed Tank weighs a minimum of 444 lbs. (201 kg). All precautions should be taken when raising the tank to its feet. Follow the instructions given later in this manual.
The safety pages show you where you can find the safety decals. The photographs show exactly where the decals should be. If a decal has been damaged or is missing contact our company for a free replacement.
First, read the assembly manual completely before starting to assemble the Bulk Feed Tank. Check the shipment with the packing list to be sure there are no shortages.
1. Decal protective mask must be removed when assembling tank. Mask may become difficult to remove if left exposed to sunlight.
2. Vertical seams must be staggered on all sidewall rings.
3. When legs extend up 2 rings, the leg holes must be in alignment in the bottom 2 rings.
4. All hopper seams and the hopper collar use truss head bolts. The heads of the bolts must be on the inside of the tank.
5. Hex head bin bolts are used on all sidewall and roof seams with the bolt heads on the outside of the bin.
6. Hex head bolts are to be used on all leg to sidewall connections with the bolt heads on the inside of the tank.
7. All bolts are to be tightened from the nut side only. Do not allow bolt heads to spin.
8. Drift punches can be used to align holes.
9. All vertical sidewall sheet seams must be overlapped in the same direction.
10. A hole spacing of 3-1/8" is used at the top of all top sidewall sheets and at the bottom of all bottom sidewall sheets.

4. General Information
Selecting the Proper Site
The selected site should be level, firm and free from underlying debris. The tank can be installed satisfactorily on slopes, but as the slope increases, additional labor and materials are required for the foundation. The concrete foundation surfaces must be level and tamped thoroughly to prevent uneven settling from the weight of the tank. Good water draina ge should be provided to prevent water collecting under or around the tank. The site mu st allow conve nient access for loading and unloading and plus provide additional space for future units. Also, consider the positioning of handling equipment, availability of electricity, etc.
. If some fill is required, it should be watered
Tools
Tools recommended for assembly of Bulk Feed Tanks.
1. Assorted sizes of combination wrenches
2. Hammer
3. 3-12" Long drift punches
4. 1 Large flathead screwdriver
5. 1 Pair of slip joint pliers
6. Two (2) adjustable wrenches
7. Ratchet and sockets

How to use charts on this page
The chart titled “Body Sheet Chart” is for the reference when building the tank. This chart tells you how many rings the specific tank must have. To read the chart find the tank size you wish to build. For example, an 12' diameter tank with 4 rings will look like BFT 12'-4 rings. The side labeled “Gauge” will tell you which body sheets to use. The sheets are color coded, simply match the gauge number with the color. (Use “Sheet Gauge Color Code Chart” on Page 27.)

IMPORTANT: Number of rings shown for each tank size are maximums. (12' 60° Tanks have a 6 ring
maximum. 15' 45° and 18' 45° tanks have an 8 ring maximum.)
NOTE: Body sheets are color coded on edges for gauge identification.
12' Sidewall Sheet Orientation
IMPORTANT: Please note sheet orientation when assembling the bin sidewall. The upper right corner
will have a slot or identifying sticker. This corner should be on the inside of the tank when assembled. (See Figure 6A.)

Sidewall Erection
12'-21' Bulk Feed Tank
12'-21' Diameters Bulk Feed Tanks are designed to be built vertically utilizing bin jacks or a crane of adequate capacity. Before bolting the sidewall sheets together, check that you have the proper gauge steel for the first ring. The higher gauge number denote the thinner materials. For example, 20 gauge material is thinner than 14 gauge. In erecting all Bulk Feed Tanks the thinnest material always goes on top, therefore the first sidewall ring you assemble will be the top ring of the tank. Check the various gauges of the tank with the color code chart and begin building accordingly. Remember assemble th e top ring first. Note ring overlap detail in Figure 6B.
NOTE: See Page 27 for proper gauges and color code chart. IMPORTANT: The number of rings shown for each tank size are maximums. (15' 60° Tanks have a
6 ring maximum, 21' 45° tanks have a 7 ring maximum. 12' 60° Tanks have a 7 ring maximum. 15' 45° Tanks have an 8 ring maximum. The 12' 45° and 18' 45° tanks have an 9 ring maximum.)

IMPORTANT: BEGIN BOLTING IN THE CENTER OF SHEETS when connecting sidewall rings to one
another. When bolting sidewall rings to one another, always begin bolting in the center of the sheet and work toward the outside edges (horizontal seams). This allows the sidewall to draw up evenly.
